I'm awful at karaoke, but if I did have to sing, I'd go for my favourite Frank Sinatra song 'I've Got You Under My Skin.' The fact I love Frank is my grandfather's doing: he drummed it into me from a very early age that Frank Sinatra is God.
If I could film, we'd film every episode of 'Doctor Who' in New York. I have an affinity with the city. It has some wonderful locations and it is devastatingly vast and huge. Central Park looks amazing on camera.
Even now, I'm very superstitious, in silly ways. I always put my left boot on first. Or on set, I always tie my bow tie from right to left.
As we get older - perhaps I'm just speaking for myself - we can get too cynical.
I am terribly clumsy, so there is a plethora of walking into lamp-posts, falling over, dropping things, and ruining sofas.
I think that, if the world was a bit more like Comic-Con, we'd all be a little happier.
Spiders - the way they move freaks me out. It's so malevolent.
Apparently, as a kid, I used to eat spiders. Maybe there's some Freudian significance behind that.
At university I had a big coloured scarf and people would often say, 'All right, Doctor Who?' And, I thought, I rather liked that notion.
Actors, movie stars, rock stars, I can meet them with no worries - but with footballers I go weak at the knees. All of them.
I'm not handsome enough to be James Bond. Maybe a villain, though.
I thought 'Skyfall' was a sumptuous film.
I am a fan of a bright sock. They're bold.
I am a fancy dress grump, to be honest.
Police boxes, tweed blazers and bow ties feel quite English, but I think that is one of his virtues, one of the strengths of 'Doctor Who.'
I always steal a pair of socks on every photo shoot I do. It's my thing.
For clothes, I like Dover Street Market and Acne. For vintage, I go to Mint just off Seven Dials. For shoes, it's Church's and Russell & Bromley.
Sometimes when you lose your mobile phone, even though it's frustrating, it's sort of rewarding in many ways because, though we do rely on them a lot, we are not reliant on them. The world continues without.
If I was making a tea advert, I would want to communicate about tea is that it can console you, it can start your day, there is the warmth and the ritual, and you can share it; you make someone a cup of tea and you offer it to them.
The storytelling in 'Doctor Who' is quite universal.
